When 24 is added to a number the result is the same as when the number is multiplied by 3?

12

Step-by-step explanation:

your equation looks like this:

x+24=3x

subtract x on both sides to get:

24=2x

divide by 2 to get:

x=12

check:

12+24=36

and

12×3=36

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
